The prospects for the use of vitamin B12 derivatives in pharmacology

Background. The structure of corrin tetrapyrrole macrocycles (compounds similar in structure to vitamin B12) is a kind of universal chemical template for targeted drug delivery, and the development of chemical sensors and antidotes. Objective: systematization of information on targeted modulation of certain corrins’ properties through chemical modifications. Material and methods . Literature analysis using modern methods of topological and metric data analysis was carried out. All relevant publications (n=863) were extracted from the PubMed/MEDLINE database on request “(cobalamin OR Cobyrinic OR vitamin B12) AND (Molecular Conformation [MeSH Terms] OR Vitamin B 12/*analogs & derivatives/*chemistry [MeSH Terms] OR Vitamin B 12/*chemistry [MeSH Terms] OR Structure-Activity Relationship [MeSH Terms])”. Results. Information was systematized on how it is possible to regulate the properties of vitamin B12 (cobalamin) derivatives by introducing specific substitutions of groups in the corrin ring, on chemical modifications of cobalamin derivatives, biosynthetic approaches to the synthesis of cobalamin derivatives, and the effects of interactions of these modified corrins with “small” inorganic and organic molecules. Conclusion. The results obtained by systematic computer analysis of publications on corrins make it possible to reasonably form samples of candidate molecules for corrin studies in silico, in vitro, and in vivo.
